i personally think there may be some hope for ed and oswald. ed did think about stabbing oswald in the back (a metaphor for betraying him, needless to say) BUT as soon as oswald apologized, he folded the knife up and put it away. basically, he didnt stab oswald in the back - literally OR metaphorically - which is why he told oswald to remember that hes his best friend. hes going to tabitha, butch, and barbara to play them. not oswald.
